Proportional valve unit "VFR series"
Integrated pressure reducing valve and flow proportional valve!
We would like to introduce an innovative product that achieves pressure adjustment and flow control in a single unit. This device allows for easy and precise flow adjustment through current control. It can continuously vary the flow rate according to the current value, and with minimal hysteresis, it enables smooth and accurate control. Additionally, it supports PWM control, allowing for integration with advanced control systems. Its design, integrated with a pressure reducing valve, mitigates the effects of primary pressure fluctuations, maintaining stable output. This product has a proven track record in devices where stable flow control is essential, such as oxygen concentrators, demonstrating its reliability. It is utilized in various fields requiring precise fluid control, including medical devices, industrial process control, and research and development equipment. By performing multiple functions in one unit, it also contributes to system simplification and cost reduction. Customization is available to meet your specific applications and requirements, so why not enhance the quality and efficiency of your products or processes with this product that combines stability, precision, and multifunctionality? For detailed specifications or inquiries about implementation, please feel free to contact us.

Introduction to the Mixing and Extrusion Molding Evaluation Test Device "Laboplast Mill"
The "Laboplastomill" is a testing device used for evaluating processing characteristics and simulating molding using small mixers and extruders. It is widely utilized by many customers in the field of polymer materials, including thermoplastic resins, thermosetting resins, and elastomers. There are various methods for testing, but it allows measurements to be conducted under conditions close to those of actual production molding processes, enabling the acquisition of practical measurement data from a small amount of samples. For more details, please refer to the attached materials. Additionally, we have a demonstration unit at our factory, so please feel free to contact us if you wish to conduct sample testing.
